`ardunno-cli-gen`

Generates nice-grpc API for the Arduino CLI from the proto files

Installing

npm i ardunno-cli-gen -S

Usage

CLI

Usage: ardunno-cli generate [options] <src>

Generates TS/JS API for the Arduino CLI

Arguments:
  src                 The source of the proto files to generate from.
                      The input source can be a path to the folder
                      which contains the proto files. The source can be
                      a valid semver. Then, the proto files will be
                      downloaded from the Arduino CLI's GitHub release.
                      It can be a GitHub commit in the following format
                      `(?<owner>)/(?<repo>)(#(?<commit>))?`. Then, the
                      proto files will be cloned and checked out from
                      GitHub.

Options:
  -o, --out <string>  Specify an output folder for all emitted files.
  -f, --force         Override previously emitted files in the output
                      location.
  -h, --help          display help for command

Examples:

# generates from local proto files
npx ardunno-cli generate ./path/to/rpc --out ./src-gen

# generates from a valid semver
npx ardunno-cli generate 0.29.0 --out ./src-gen

# generates from the HEAD of the default branch
npx ardunno-cli generate arduino/arduino-cli --out ./src-gen

# generates from a specific commit
npx ardunno-cli generate arduino/arduino-cli#5a4ffe0 --out ./src-gen

# generates from a specific branch of a fork
npx ardunno-cli generate cmaglie/arduino-cli#alternate-homedir --out ./src-gen

API

CommonJS:

const { generate } = require('ardunno-cli-gen');

TypeScript:

import { generate } from 'ardunno-cli-gen';

Generate:

// `src` is a path like, a valid semver or a GitHub ref as `(?<owner>)/(?<repo>)(#(?<commit>))?`
// `out` is the output folder
// user `force` if you want to override the generated output
await generate({ src: '0.29.0', out: './src-gen', force: true });

Running the tests

npm run test

Using

nice-grpc - A TypeScript gRPC library that is nice to you
ts-proto - An idiomatic protobuf generator for TypeScript
protobufjs - Protocol Buffers for JavaScript (& TypeScript)
protoc - A simple wrapper for the protoc

Notes

The underlying protoc version is 3.20.3. It comes from the protoc dependency. protoc is not required on the $PATH
```
npx protoc --version
libprotoc 3.20.3
```

Use debug to log additional details

% DEBUG=ardunno-cli* npx ardunno-cli generate ./path/to/rpc --out ./src-gen

Run the generator from the sources (or use the predefined generate VS Code task):
- npm run compile
- `node dist/cli.js generate 0.32.2 --out ./gen-output
